Hi Ina, I'm new on this site. I recently made a Q with LOTS of seams to match. Something I never thought of made a big problem. That was that one of the fabrics was thinner and with a lower thread count. This made it stretchier than the others, thus the seams were off. This might help, though: somewhere I learned that you can stick a pin into the seam at the exact point to be matched then into the exact point in the other seam. Make sure the pin is vertical to the seams, then pin closely on both sides of it along the seam allowance. Leave the vertical pin in place until you have to remove it as you sew. This helps. Also. if the match is tricky, sew just the fraction of an inch that covers the matched seams. Then check to see whether you've nailed it. If so, scream with joy and finish the seam; if not you'll have only a few stitches to undo instead of a long seam. (The next Q I make will not have 8 seams coming together!) Hope this helps, Anne
